The device operates from 2.3V to 6V input, making it ideal for single-cell Li-Ion or USB-powered applications requiring a 3.3V rail. The DCS-Control (Direct Control with Seamless transition) topology provides fast transient response with seamless transition between PWM and power-save modes. The 2.5MHz switching frequency allows use of tiny chip inductors. In power-save mode, the quiescent current is only 17uA typical, preserving battery life. The device supports 100% duty cycle mode for lowest dropout operation when the input voltage approaches the output voltage. The fixed 3.3V output eliminates external feedback resistors, further reducing solution size.","working_principle":"The TPS6209733RWKT uses TI's DCS-Control topology. (1) DCS-Control: A proprietary control scheme that combines voltage-mode control with a fast output voltage comparator. The comparator provides immediate response to output voltage deviations, while the voltage-mode loop maintains precise DC regulation. (2) PWM Mode: At load currents above the power-save threshold, the device operates in fixed-frequency PWM mode at 2.5MHz, providing low output ripple. (3) Power-Save Mode: At light loads, the device enters PFM (pulse-frequency modulation) mode where single switching pulses are delivered on demand, reducing the effective switching frequency and quiescent current to 17uA. (4) Seamless Transition: The DCS-Control architecture ensures smooth transition between PWM and PFM modes without output voltage dips or overshoots. (5) 100% Duty Cycle: When VIN approaches VOUT, the high-side MOSFET is held on continuously, eliminating switching losses and providing the lowest possible dropout voltage.","pin_description":"
